It uses a single-pole, single-throw circuit with 2 blade terminals, giving a straightforward on\/off control for lighting, pumps, fans, and other 12 volt accessory circuits rated up to 20 amps.\u003c\/p\u003e\u003cp\u003eConstruction is stamped brass and injection molded nylon, with silver tin oxide contacts inside the switch body for dependable, low-resistance switching over repeated cycles. The Contura Rocker Switch line is engineered to withstand the marine environment: it is vibration, shock, thermoshock, moisture, and salt spray resistant, with an operating temperature range from -40 degrees Celsius to 85 degrees Celsius. It carries UL1500 and ISO8846 ignition protection ratings for use on marine products, and an IP66 rating for the front panel components, meaning the visible rocker face resists dust and powerful water jets when properly panel-mounted.\u003c\/p\u003e\u003cp\u003eThe rocker measures 13\/16 inch by 1-7\/16 inch, a common panel cutout size, making it a straightforward drop-in for helm stations, dash panels, and accessory switch panels already using this footprint.
